Proc. ASME. HT2021, ASME 2021 Heat Transfer Summer Conference, V001T04A003, June 16–18, 2021
Paper No: HT2021-62615
... Abstract Film cooling performance of the cylindrical film holes and the bifurcated film holes on the leading edge model of the turbine blade are investigated in this paper. The suitability of different turbulence models to predict local and average film cooling effectiveness is validated...
Proc. ASME. HT2021, ASME 2021 Heat Transfer Summer Conference, V001T04A004, June 16–18, 2021
Paper No: HT2021-63467
... Abstract A numerical study has been performed to validate the multiphase CFD model (DPM) by comparing its results to the experimental data of an air/mist film cooling study. The complete experimental test section was simulated including all the details including all the five holes, side walls...

... of the air/mist fluid flow inside and outside the vanes as well as the heat conduction through the vane body. The complete 3-D vane with internal cooling passages and external film cooling holes on the surface is simulated in a rotational periodic sector. The discrete phase model (DPM) is used to simulate...

Paper No: HT2019-3401
... Abstract In modern gas turbines, film cooling is the most common and efficient way to provide thermal protection for hot components. Secondary holes to a primary film cooling hole are used to improve film cooling performance by creating anti-kidney vortices, a technique that has been well...
